Mariners left-hander Marco Gonzales will undergo season-ending surgery for the nerve issue in his forearm, per Daniel Kramer of MLB.com. The lefty says the recovery time is a matter of months and he will be able to begin his offseason preparations on schedule with the hope of being ready for Spring Training. He is already on the 60-day injured list.
Gonzales, 31, began the year in Seattle’s rotation but landed on the IL in early June due a forearm strain. He didn’t seem to get on a track towards a return, having been shut down in late June and never getting sent on a rehab assignment. It appears that he and the club have exhausted any non-surgical options they explored and he will now have to go under the knife. He will finish 2023 with an ERA of 5.22 over 10 starts and 50 innings pitched.
It will ultimately go down as a disappointing and frustrating year for Gonzales, but it seems there’s some light at the end of the tunnel since he expects to have a fairly normal offseason and Spring Training. 2024 will be the final guaranteed season of the extension he and the club signed in 2020, with the southpaw set to make $12MM next year, with the club having a $15MM option for 2025 with no buyout.
The Seattle rotation has lost two of its Opening Day fivesome, as Robbie Ray required Tommy John surgery in May and Gonzales ended up missing most of the year. The club has fared well despite those losses, as Luis Castillo, George Kirby and Logan Gilbert have been joined by rookies Bryan Woo, Bryce Miller and Emerson Hancock. Woo is on the injured list but isn’t expected to miss much time. Even without him, the club still has a strong front five and is in the thick of a playoff race.
All of those players are either under contract or club control next year, which should give the club a strong on-paper rotation going into next year. If Gonzales is healthy, they have seven viable rotation members, even before counting a midseason return of Ray. Their starters already drew trade interest prior to the summer deadline but the Mariners ended up hanging onto them. Perhaps they could revisit those talks in the offseason if everyone is healthy and they have a chance to upgrade another part of their roster, though they could also opt for retaining the rookies as optional depth.
